Description

Technical Field

[0001] The present application belongs to the field of containers for material storage or transportation, and in particular, relates to a mineral powder storage and transportation device. Background Art

[0002] After the mineral powder is produced, if it cannot be sold in time or transported over long distances, it is necessary to use a mineral powder storage device to store the mineral powder. For example, when the mineral powder is stored in a container, the mineral powder may form lumps inside the container due to the mutual squeezing of the mineral powder. The mutually compacted mineral powder may also easily cause difficulty in discharging.

[0043] Example 6

[0044] A mineral powder storage and conveying device, wherein a heating layer is provided in the tank body 26, a heating core is provided in the tank body vibration rod 4 connected to the seat body vibration rod 18, and an exhaust valve and a temperature sensor for monitoring the internal temperature of the tank body 26 and a humidity sensor for monitoring the internal humidity are provided on the cover body 5. The structure and connection relationship of the remaining parts are the same as those described in any one of the aforementioned embodiments, and will not be repeated here to avoid cumbersome text.

[0045] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0046] In the present application, the leg 10 slides along the guide connecting column 6 through the slide groove of the leg top seat 9. When the tank body 26 vibrates due to the vibration caused by the transportation process or the linear oscillation motor 16, the tank body 26 will move with a small amplitude along the direction of its own central axis. The vibration of the tank body 26 will cause the leg top seat 9 to slide relatively along the guide connecting column 6 through its own slide groove. The slide groove of the leg top seat 9 can limit the rotation of the tank body 26 in the circumferential direction.

[0047] The movement of the leg top seat 9 along the guide connecting column 6 causes a change in the relative position between the leg top seat 9 and the vibration adjustment seat 7, which in turn compresses or releases the vibration spring 8, causing the vibration spring 8 to undergo elastic deformation, thereby assisting the tank body 26 to move along its own central axis.

[0048] The vibration adjustment seat 7 moves with the tank body 26, and the leg top seat 9 is located on the leg 10. The tank body 26 moves relative to the tank body vibration rod 4, so that the auxiliary rod 20 moves relative to the tank body 26, thereby effectively loosening the mineral powder at the position where the auxiliary rod 20 is located, avoiding compaction of the mineral powder at this position due to extrusion.

[0049] Since the mineral powder at the bottom of the tank body 26 is squeezed by the mineral powder above and is severely compacted, a plurality of discharge augers 21 are arranged at the conical cylinder position at the bottom end of the tank body 26. The discharge augers 21 extend into the conical cylinder for a certain distance. The rotation of the discharge augers 21 loosens the mineral powder at this position, thereby promoting the discharge of the mineral powder from the discharge port 13.

[0050] The high-pressure nozzle 27 above the discharging auger 21 can purge the mineral powder on the inner wall of the conical cylinder after the mineral powder is discharged, so as to clean the inner wall. At the same time, when the mineral powder is not completely discharged, a certain amount of high-pressure gas can be introduced to loosen the mineral powder at the position of the high-pressure nozzle 27, thereby separating it from the inner wall of the conical cylinder.

[0051] In the present application, the tank body 26 is provided with a tank body ring edge 28 at the top circumferential edge position, and the tank body ring edge 28 is a protruding ring body fixed as one with the tank body 26. The tank body Z-shaped connecting groove 25 is processed on the circumferential side wall of the tank body ring edge 28, and the tank body Z-shaped connecting groove 25 includes multiple sections of horizontal guide grooves and longitudinal guide grooves connecting the multiple sections of horizontal guide grooves. The tank body Z-shaped connecting groove 25 can cooperate with the cover body fixing piece 17. In the process of connecting the cover body 5, the cover body 5 gradually applies a force to the sealing ring 23 to ensure the sealing performance.

[0052] In the present application, a heating layer is provided in the tank body 26, a heating cell is provided in the tank body vibration rod 4 connected to the seat body vibration rod 18, and an exhaust valve and a temperature sensor for monitoring the internal temperature of the tank body 26 and a humidity sensor for monitoring the internal humidity are provided on the cover body 5. The above structure can prevent the mineral powder inside the tank body 26 from being easily affected by moisture, thereby avoiding the problem of the mineral powder (including active mineral powder) being affected by moisture and agglomerating, and improving the storage effect. Moreover, the heating structure can cooperate with the above vibration structure to improve the storage effect of the mineral powder.

[0053] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
